Verifying the hash values as we are currently doing results in iterating every type record before the user even tries to access the first one, and the API user has no control over, or ability to hook into this process. As a result, when the user wants to iterate over types to print them or index them, this results in a second iteration over the same list of types. When there's upwards of 1,000,000 type records, this is obviously quite undesirable. This patch raises the verification outside of TpiStream , and llvm-pdbdump hooks a hash verification visitor into the normal dumping process. So we still verify the hash records, but we can do it while not requiring a second iteration over the type stream.
